The DELL H339D RAM module is an entry-level memory upgrade designed to enhance the performance of compatible Dell servers and workstations by providing an additional 1GB of DDR3 memory. Operating at a speed of 1066MHz, this module is capable of increasing the responsiveness of the system by facilitating faster data processing compared to older generations of RAM. The 1Rx8 configuration signifies a single rank of memory, making it a cost-efficient solution for boosting system memory. As a PC3-8500R module, it is registered (buffered), which means it includes a register that acts as a buffer between the DRAM modules and the system's memory controller. This buffer contributes to system stability and reliability, particularly in environments where data integrity is paramount. Suitable for small-scale server and workstation upgrades, the DELL H339D is engineered to meet Dell's precise specifications, ensuring compatibility and reliable performance in supported systems.
